Title: Thermal stabilizing of filtration membrane
Inventor: SHIMODA AKIYOSHI
IPC: B01D67/00
Filed: 1995-04-07
Abstract: PURPOSE: To obtain a filtration membrane highly thermally stabilized without drastically lowering water permeability by heat-treating an amorphous aromatic polyether ketone filtration membrane while keeping wetting state in the presence of thermally stabilizing solvent at a temp. equal to or above the glass transition point and equal to or below the melting point of the aromatic polyether ketone. CONSTITUTION: This filtration membrane useful as an ultrafiltration membrane or a microfiltration membrane used for filtration or sterilization for preparing an extrapure water for electronic industry or medical application is thermally stabilized by heat-treating the amorphous aromatic polyether ketone(PEK) filtration membrane while keeping wetting state in the presence of the thermally stabilizing solvent at the temp. equal to or above the glass transition point and equal to or below the m.p. of the PEK. The low b.p. solvent present in the membrane before treating is removed by replacing with the thermal stabilizing solvent. As a result, the filtration membrane excellent in fractionation ability is stably obtained, and the lowering of the water permeability is improved by incorporating a high molecular compound into the membrane before the heat treatment.

Title: Power steering device in industrial vehicles
Inventor: ICHIKAWA TOKIHIKO
IPC: B62D5/04
Filed: 1984-04-23
Abstract: PURPOSE:To secure a motor-operated power steering device, by using an electric motor for a power source of a booster. CONSTITUTION:When a steering main shaft is operated in rotation clockwise, this turning force is transmitted to a driven shaft 14 from a driving shaft via an elastic body 18. At that time, with elastic deformation in the elastic body 18, a driving plate 9 turns a limit switch R1 for right steering detection use at the first set, to ON operation whereby a motor shaft 11 is rotated clockwise. And, in the case where steering load is large enough, deformation in the elastic body 18 is also large so that another limit switch R2 at the second set is also operated. If so, the electric motor is energized with current through a high torque circuit. That is to say, the electric motor outputs torque by stages in a manner conformable to the steering load.

Abstract: PURPOSE:To release storage in accordance with the idle state of a bus and to make the usage of the bus uniform by storing the acquisition of a bus using right for a bus request, and when another bus master having the same level uses the bus, inhibiting the repeated request of bus usage. CONSTITUTION:When the bus is acquired by a certain bus using request signal, the acquisition is stored in an FF or the like of a bus acquisition controlling circuit and the sending of the succeeding bus request signal is inhibited. When all other bus requesters having the same bus master level are not requesting the bus, the storrage is released and the succeeding bus requesting signal is sent by the 1st bus acquiring function. After a prescribed period under the bus usage inhibiting state by the 1st function, the bus usage requesting signal is switched to a bus usage requesting signal having an upper level by the 2nd bus acquiring function. The 1st and 2nd bus acquiring functions are constituted by a daisy chain logic and the usage of the bus is made uniform.

Title: Starting fuel correction device for efi engine
Inventor: AOI TOMIO
IPC: F02D41/06
Filed: 1980-06-20
Abstract: PURPOSE: To prevent contamination coverage on plugs in an EFI engine by prohibiting the injection when the device's main swtich is repeated on and off again for a device to determine the amount of injection according to the relation between the engine temperature and requisite fuel injection time at the time of starting.  
     CONSTITUTION: The relation between the engine temperature TE and injection time signal Ti is stored in a memory 1. When the main switch S is turned on and the terminal voltage exceeds the reference voltage Es, a comparator 9 will give an output and the monomulti 10 yields the pulsation output. Signals from the memory 1 is led in, at the same time, through a resistor 2 and a preset down counter 3 as a signal decreasing by steps, and further forwarded to a flipflop 6 controlling the injection solenoid. Even if the main switch S is turned on again before the preset time, the monomulti 10 will not give any output because the output of comparator 9 is still held in the condition "1".

Filed: 1978-07-07
Abstract: PURPOSE:To achieve the improvement in the energy conversion efficiency of a step motor and achiev the improvement in space efficiency by electromagnetically serially constituting two coils which are disposed nearly parallel. CONSTITUTION:Stators 21, 22 which are coupled to magnetic cores 17, 18 have semicircular end faces 21a, 22a so as to oppose to a rotor 16. The driving pulse currents applied from the circuit including a time standard source are flowed alternately from O1 to O2 and from O2 to O1 to the coils 19, 20 wound on the magnetic cores 17, 18 to excite the coils, whereby the magnetic path of the stators 21, 22 and rotor 16 is formed. Then, the coil winding length is doubled as compared to that of ordinary ones and this enables the longer coils to be constituted with smaller coil winding diameters, making possible the motor of higher output torque and lower current consumption. When the plane space and output torque are made the same, the thickness becomes half that.

Abstract: PROBLEM TO BE SOLVED: To decrease a cutting resistance and improve a surface roughness by mounting throw away tips whose phases of a regular polygonal of a cutting edge are different from a tip mounting flat surface to a plurality of tip mounting seats arranged with a common mounting angle. SOLUTION: A plurality of tip mounting seats 4 are arranged to the circumference of a cutting edge head 1. As for the most popular type of the tip mounting seats 4, a tip mounting screw 6 is provided at the center portion of a flat seat surface 5 and an abutting wall 7 for preventing self-rotation of tips 8 is provided. The tips 8 are fixed to the tip mounting seats 4 by mounting bolts 9. In this instance, the tip mounting flat surface of the tip 8 and the phase of a regular polygonal cutting edge are arbitrarily selected, thereby changing a face angle formed between a minor cutting edge of the tip 8 and a surface to be cut and an approach angle formed between an incline of a major cutting edge and a central axis of a cutting edge head 1. Consequently, the tips 8 function mutually, thereby contributing decrease in cutting resistance and improvement of surface roughness.

Abstract: PURPOSE:To prevent a part of document from being left on a guiding member by feeding the document by as much as a feeding amount obtained by adding a previously set amount to a specified amount in the case of feeding the document to a contact glass. CONSTITUTION:When the document is started to be fed and the leading edge of the document is detected by a timing switch 3, a driving motor is driven to be reversly rotated so as to feed the document sent from a return path 20 to a contact guide 7 side. Continuously, the number of pulses (P1+P2) set by a feeding amount setting means is started to be counted after the trailing edge of the document is detected by the switch 3. The number of pulses P1 means the specified number of pulses from detecting the trailing edge of the document till feeding the document to a regular placing position on the guide 7. Meanwhile, the number of pulses P2 means additional feeding amount for specially feeding the document by specified dimension L to the upstream side from the regular placing position. Thus, that the trailing edge of the document is stopped in a state where it is caught by the guiding member 22, which is caused by the variance of the actual feeding amount, is prevented.
